Question 241855
Variables are: a, b, c
Let a = 4
Let c = 8.3
We need to find b.
.
The equation then becomes:
{{{3(a-b)-1=c}}}
{{{3(4-b)-1=8.3}}}
{{{12-3b-1=8.3}}}
{{{-3b=8.3-12+1}}}
{{{-3b=-2.7}}}
{{{b=0.9}}}
.
*** We are not getting an integer for a result.  Did you really mean to type 8.3 or 8?  I'm going to work it out for 8 just in case, because we would end up with an integer as a result.
.
{{{3(a-b)-1=c}}}
{{{3(4-b)-1=8}}}
{{{12-3b-1=8}}}
{{{-3b=8-12+1}}}
{{{-3b=-3}}}
{{{b=1}}}
.
I hope this helped.
